Dr. Trojanowska’s research is aimed at understanding the molecular and cellular mechanisms that regulate ECM synthesis in healthy tissues and in pathological conditions such as fibrosis and tumorigenesis. The majority of her studies focus on the pathogenesis of scleroderma, an autoimmune disease characterized by vascular abnormalities and a prominent fibrosis of the skin. Her laboratory uses molecular and cellular approaches and various experimental models to elucidate the mechanisms responsible for uncontrolled ECM deposition and vessel degeneration in scleroderma. The second area of investigation is related to activation of tumor stroma. These studies examine the molecular mechanisms that mediate controlled regulation of ECM turnover in healthy connective tissue and are responsible for dysregulation of this process during tumorigenesis. Recent studies together with Dr. Lafyatis are examining the role of ER stress in systemic sclerosis.
